Additional information

No reliable studies (Klimisch 1 or 2) on toxicity of vanadium substances to sediment organisms are available. A study (Conestoga-Rovers & Associates, 2009; Klimisch 3) on the toxicity of field-contaminated sediments enriched with both V and Mo by metallurgical activities did not show a significant toxic effect on growth and survival to Hyallela azteca in a 10-day test with sediments containing up to 503 and 1590 mg V/kg dry weight.
